I have one providing full off grid power to my house. It replaced two 6500s. I guess I'm still enjoying the honeymoon because the 18k's performance is such an incredible improvement over the 6500s! I don't notice any flickering but do notice my fireplace insert blower motor slows slightly when I drop either the 5kW dryer or the 4.8kW water heater on it - but that is understandable. No light flicker with the unit loaded to 11.2kW.

How heavily is the unit loaded? Also are your fans small HP or part of a large ventilation system?
Small fan on wood stove. No more than 3k flowing through unit
Likely because it's drawing some grid along with batts and solar, even though it doesn't show it, at least that's how mine is working. When it shows no grid use I can still see 3-6amps use from grid on each grid leg with amp meter. Kinda sucks. I go to off grid mode and that stops but then I get the fluctuating power

What firmware are you running? I’ve been using mine off grid for over 9 months. I don’t have any fluctuations or flickering.
I have 18kPV off grid only and when I turn off a 5kW resistive heater the lights flicker once immediately when the heating element is turned off (fan still running). This is also with less than 1kW of other loads besides that one.
